Imagination inflation is a fact, not an artifact: A reply to Pezdek and Eddy

Pezdek and Eddy (2001) claim to prove that imagination inflation is a spuri ous effect caused by regression to the mean (RTM). They make four predictio ns about what patterns of data would demonstrate a genuine effect for imagi nation versus those that would be explainable by RTM. We review each of tho se predictions, and demonstrate significant problems with them. We conclude that imagination inflation is a genuine effect, and that Pezdek and Eddy's work has contributed to the growing research showing that when people imag ine fictitious events from long ago, they become more confident that those false events were genuine experiences.
